Compared to the more delicate strikes that require more accurate distance control and more consistent ball response when in contact with the ground, these same hardness and rotational characteristics are not required. wnns, use...1~问八, It is important for players to have a match for a wilderness. Balls of different hardness and/or made of different materials will react differently when struck with different clubs (for example, producing a different hardness sensor), producing different Sound, etc.). A ball formed to move away from the nickname wood for a long or maximum distance may feel too hard for at least some of the player's preferences and/or produce an unnecessary sound (eg, a large click (click) or Ping. - Softer balls that produce more rotation (and usually move shorter distances) also produce sounds that are unnecessary for at least some players' preferences (ie, it will be produced when hit by a club) A more "squeak, type of sound", and it will not move the required distance during longer strikes. Therefore, the selection - the ball will require players to balance their performance and "sensing, requirements and needs. Ball construction And the sensing characteristics are definitely not a "one size fits all, the theme. The golf pit pattern is not the same size for all": shape. For example, players with lower swing speeds will need to help The ball No. 1 has a better lift when it hits to give the player a better distance - the pit pattern. However, if it has a - high swing speed: a player uses the same pit pattern will make the ball At the beginning of its flight ^ Rise _call, ''lead to reduce the distance from the i-wood. = On the one hand, it provides a good pitch for controlling the ball trajectory and the high swing speed of the money (ie, 'leaving the 1st wood'). Make the ball fly a short distance when hit by a wooden pole 201208740 at a lower swing speed.

As shown in Fig. 2A, the recess 108 has a circular arc cross-sectional shape (an arc formed in the cover layer 106 of the ball), wherein the cross-sectional length of the inner surface 108a of the recess 108 (in the first At least 75% of the point in the point 2A [between 丨 and !^) has a single half gRd. In other words, in this example, at least 75% of the center of the pit surface 108a constitutes a sector or portion of a spherical surface having a radius Rd. When the dimple in the golf ball according to the example of the present invention has a circular arc cross-sectional shape, as will be explained in more detail below, the dimple radius Rd may have one of a plurality of values in the dimple configuration according to the present invention. range. If desired, the dimples according to at least some examples of the present invention may have an acute or sharp corner at the junction of the surface 106a of the cover layer 106 and the inner surface 108a of the dimple 108. However, often, as shown in Fig. 2A, the edge of the recess 37 201208740 will be more rounded, for example, having an edge radius 匕. While a desired edge radius may be provided in a dimple configuration in accordance with an example of the present invention, in some more specific examples, the edge radius Re will be in the range of one of 〇1 to 5111111, and in some instances, It is in the range of 〇·25 to 3 mm or even in the range of 0.25 to 1.5 mm. Some of the ball examples in accordance with the present invention will have an edge radius r of about 0.5 mm, which may be the same or different for various pits on a given golf ball construction. Even when the final edge of the dimple 108 has a different shape (e.g., a rounded corner or edge) to facilitate the transfer between the inner dimple surface 10a and the outermost cover surface i〇6a, the dimple 108 can still be considered to have a spherical sector shape and a circular cross-sectional shape. As used in this specification, if 75% of the cross-sectional surface 108a of a pit constitutes an arc of a circle, the pit will be considered to have a circular cross-sectional shape and if the center of the surface area of the pit is 75 % constitutes a part of a sphere and the pit will be considered to have a spherical sector shape. Figure 2B shows other features that may be included in the configuration of the pits in accordance with at least some examples of the present invention. As shown in Fig. 2B, an imaginary line (dashed line pL) shows the position where the surface l〇6a of the outermost cover layer 106 of the golf ball will be set if the pit 1〇8 is not on the ball. The edges (or perimeters) of the pits 1〇8 can be determined by locating the points E, and at the E points, the tangent lines on the opposite sides of the pits 1〇8 are parallel (to thereby provide 2 B in the single dotted line TL). These tangent points E are bounded by the edge of the pit log, and for a pit having a circumferential edge, the distance between the opposite tangent points E is defined as the "diameter" d of the pit, and in this description Use this term. For pits with other 38 201208740 perimeter shapes (eg, polygons, ellipses, ovals, etc.), a similar pit size can be defined, such as length, width, long axis, short car, large radius, small Radius, chord length, diagonal length, etc. The "depth" of the pit used in this specification means the size of the pit from its deepest point to the tangent TL, as shown in Fig. 2B. For a spherical sector shaped dimple having a circular arc cross-sectional shape, the "depth" of the dimple will be at the geometric center of the dimple 108 from the tangent TL to the inner surface 108a of the dimple in the center of the dimple 108 measuring. Another pit "depth" value can be obtained from the imaginary surface of the golf ball to the deepest point of the pit (for the scalloped pit, the imaginary line p L is in the center of the pit 108 To the inner surface of the pit 1 〇 8 a is in the center of the pit 108). In this specification, when the term "depth" is used without further explanation or qualifier, the depth of the pit from the tangent TL to the deepest point of the pit is indicated (in this specification) It may also be referred to as "flat crown-pit depth" because it is measured by a plane or "cover" defined by a plurality of tangent lines TL extending between the edge E of the pit and defining the edge E of the pit. When the depth from the imaginary line PL to the deepest point of the pit is indicated, the term "total pit depth" will be used particularly in this specification (the line of the total pit depth deviates from the concave in the 2B pattern) The center of the pit 108 is shown to avoid obscuring the depth of the flat crown pit). At least two different pit volumes may also be defined for a particular pit. A pit volume is defined as the volume between a plurality of tangent lines TL extending between the pit edges E and defining the pit edges E and the pit surfaces (e.g., surface 108a as shown in Fig. 28). In this specification the volume may also be referred to as "flat crown-pitted volume" because it is defined by the plane or "crown" defined by the majority of the tangent TL group extending between the edge E of the pit and defining the edge of the hole 2012E. Cap)''Measurement. A second pit volume may be defined between an imaginary sphere of the ball (ie, where the sphere would be if the pit is absent) and the pit surface (eg, surface 108a as shown in FIG. 2B) volume of. In this specification, when the term "volume" is used without further explanation or qualifier, it is intended to indicate a pit measured by a plurality of tangent lines TL defining the periphery of the pit to the surface of the pit. Volume (the "flat crown-pitted volume"). The term "total pit volume" will be particularly used in this specification when indicating the volume measured between the imaginary sphere and the pit surface. Figure 2C shows other pit features that may be discussed in this specification and used to define at least some aspects of the present invention. Figure 2C shows various features of the thickness of the cover layer 106. As shown in Fig. 2C, the cover layer 106 of a golf ball does not have a fixed thickness due to its pits 108. Accordingly, the terms "cover thickness" and "nominal thickness" as used in this specification mean that at a location along one of the spheres of the sphere, at a location away from any of the pockets 108, at the pit 108 The thickness of the cover layer 106 is measured between the interlaced lattices or the land area. An example of such "cover thickness" and "nominal thickness" dimensions is shown as size "T" in Figure 2C. Figure 2C shows another overlay size, dimension B, which is the overlay size along the radius of one of the spheres of the sphere at the deepest point of a pit 108. A pocket on a golf ball in accordance with at least some examples of the present invention can have a wide range of B/T values, such as from 0.4 to 0.95, and in some instances, from 0.5 to 0.9, or even 0.6. To the extent of 0.85. The B/T ratio can be different for various different pit forms on a given sphere. 40 201208740 Certain aspects of the invention may also relate to the surface area coverage of the pits on the ball. For a single pit, the surface area of the pit can be defined by the area defined by the edge of the pit as described above. For a pit having a circular peripheral shape, as shown in Fig. 2D, this area can be defined as 7UX(d/2)2 (where "d" is the independent pit diameter), and the pair has a square perimeter In the case of a pit of a shape, this area can be defined as s2 (where "s" is the length of one of the edges of the pit), and for a pit having a rectangular peripheral shape, this area can be defined as lxw (where "Γ is the length of one of the edges of the pit and "w" is the length of one of the adjacent edges of the pit). Other independent pit areas may be used to determine the shape of one of the perimeters of a flat crown. The same general manner of area is determined. The total pit area (parameter Ad is the independent pit surface area) is the surface area of one of the imaginary surfaces of the ball (the parameter Ab is assumed to be that the ball does not include the pit from the outermost surface of the ball) The ratio of surface area) may be at least 70%, and in some instances, at least 72% or in the range from 72% to 85% or even in the range from 72% to 78%. In at least some examples of the invention in which all of the dimples have a rounded periphery, the ratio Ad/Ab can be In any of the above ranges, wherein Ad* is one of the total pit surface coverage areas determined by the formula (I): Μ

Ad=Art; rx(dn/2)2 Equation (1)' n=l where “Μ” is the total number of pits on the golf ball, and “d” is a separate pit diameter, and wherein Ab is as The assumption determined by equation (II) is that there is no pit present on the total golf surface area of the ball: 41 201208740

Ab = 4Kx (D / 2) 2 Formula (Π), where "D" is the outermost diameter of one of the golf balls. Many of the above descriptions relate to pits having a rounded cross-sectional shape and a circular peripheral shape. These are not necessary in all aspects of the invention. Conversely, the dimples contained in the golf ball according to some examples of the present invention may have a variety of different cross-sectional shapes, peripheral shapes, and the like. 2Eg] shows another example of a pit surface in which the cross-sectional shape has a "double radius" configuration. More specifically, as shown in FIG. 2E, the central portion of the pit 2〇8 includes a portion (or periphery) having a first radius of curvature (Rdi) (ie, toward the pit) a portion of the edge) and a lower (or central) portion of a second radius of curvature (Rd2) (ie, a portion toward the center of the pit) where the center of each radius of curvature is outside the sphere . Rdi may be greater or less than Re, and in certain examples of the invention, Rdl may be in the range of 〇.2Rd2 to 5Rd2, and in some instances, from 〇25Rd2 to 4Rd2 or even 0.5Rd2 to 2Rd2. Balls in accordance with at least some examples of the present invention may also have a three (or more) radius configuration. Fig. 2F shows an example of the shape of another pit cross section. In this example, the upper (or peripheral) portion of the dimple 218 (i.e., the portion toward the edge of the dimple) has a first radius of curvature (Rdl) and the dimple 218 is below (or central). The portion (i.e., the portion toward the center of the pit) has a flat or substantially flat bottom structure. If necessary, the central portion of the bottom of the four pits may have a convex shape (i.e., protrude outward toward the outer surface of the ball). Other dimple cross-sectional shapes may be provided in a golf ball according to at least some examples of the present invention, such as a dimple having an annular ring (projected from the inner surface of the dimple or cut into the surface of the dimple 42 201208740) with cut-in Any desired shape of the recess in one of the inner surfaces of the recess has a bump having any desired shape raised by the inner recess surface, a plurality of planar recess inner surfaces, a cylindrical recess surface, and the like. The dimples on a golf ball may have different peripheral shapes, such as polygons (eg, triangles, squares, rectangles, pentagons, hexagons, octagons, etc.), ovals, without departing from the invention. , printed shape, teardrop shape, sapphire sphere, star, irregular shape, etc. If, when the pits are formed in the cover layer (for example, during molding, prayer, etc.), a pit is different from the other pit in any obvious manner, such as in diameter, depth, volume, surface area. In terms of cross-sectional shape, etc., the two dimples will have different "forms" as the term is used in this specification. If there is more than 4% difference in any of the above dimensions or properties, the pits are "significantly" different. If, when the dimples are molded, cast, or otherwise initiated, the two dimples have the same size and shape (eg, the same diameter, depth, radius, volume, surface area, cross-sectional shape, etc.), ie, If the pits are not "significantly" different (more than 4% difference in any of the above dimensions or properties), the two pits will have the same "form". As used in this specification, even if some variation will exist for each pit in a given form, subsequent processing of the surface of the ball, such as painting, clear coating, etc., will not result in a concave shape. The pit changes into another form of pit. Polishing or polishing the ball (for example, if these processes are necessary, surrounding the seam line) will generally not be considered to be changed from one pit form to another, unless the buffing or polishing is " Obviously "changing one or more of the above dimensions or properties (eg, changing the dimension by more than 4%) and/or unless the buffing or polishing attempt changes the size of one or more of the individual dimples to match the 2012 20124040 to match The size of another pit form. 3. Pit Arrangement and Features Various aspects of the present invention relate to the form and features of the arrangement and arrangement of the pits on the surface of the golf ball. Figures 3A and 3B assist in showing certain arrangements and configuration features in accordance with aspects of the present invention. First, as shown in these figures, the golf ball 300 includes two halves 300a and 300b, each of which has a substantially hemispherical shape, but as shown in the front view of Fig. 3B, the ball halves 300a and 300b may be Curved or stepped to assist in providing a seam line 8 on the ball that does not correspond to a "big circle" or equator around one of the balls. In this manner, the ball 300 can have a "seamless, appearance, including all of the great circles on the ball 300 that are at the equator of the ball - the big circle (halfway between the poles P) a pit intersection (there is no obvious seam line where the mold halves are joined when the ball is manufactured). The pits of the golf ball 300 (in this configuration example, forms a to E) are disposed in the respective halves 300a. And N of the overlapping sectors 302 in 300b, where N is an integer in the range of 2 to 10, and in some examples from 2 to § or even from 3 to 6. In Figures 3A and 3B In a specific example, for a total of six sectors on the entire surface of the ball, each ball half 3〇 (^ and 3〇〇13 includes three sectors 302 that overlap the pole P (each sector) The zone 302 covers 120° of the periphery of the ball. The individual sector 3〇2 in the pit arrangement includes a line of symmetry LS (as indicated by a dashed line in Fig. 3A), and the symmetry line LS The independent pits (and the pit portions) in the sector on the _ side are arranged to be independent pits in the same sector 3 〇 2 on the other side of the symmetry line LS (and Pit section) 44 201208740 Into-mirror. If necessary, one or more sectors can be placed in a concave kgl case that does not include a symmetry line, for example, a sectoral replacement with a symmetry line. The identifiable sector of the dimples that do not require a sphere on the present invention must include a line of symmetry. As shown in Figure 3A, each sector 3〇2 has a spherical triangular region. If necessary (but not necessary) At least some of the sectors of the sector 3〇2 may share a common point or even a common side. In the structural example shown in FIG. 3A, the sector 3〇2 in each of the hemispheres 300a and 300b shares the same. One of the poles of the sphere P. Or, if desired, the sectors 3〇2 do not have to share a common point (eg, the spherical triangle can be separated downward by the pole p) and/or they do not have to share a common edge (eg, Other, different sectors may be disposed between the sectors 302 having the same pit pattern.) Although the pit pattern half on the ball half 3〇〇a (ie, the pit arrangement and configuration) a pit pattern half on the other ball half 3〇〇b (ie, the The dimple arrangement and arrangement are the same, but the dimples are not arranged in a mirror image across the seam line SL. Conversely, as can be seen from Figure 3B, the dimple pattern halves 300a and 300b span the seam line The sl positions are rotationally offset from each other by 2° to 90°, 5 to 60. '5 to 45., 10 to 45, 10 to 3, and even 15 to 30. Offset. In the example shown in Figures 3A and 3B, the rotational offset is about 60. Without requiring any deviation from the present invention, any desired number of all pits can be included on the ball. For example, from 320 to 432 all pits, or even 330 to 392 all pits. Some *specific golf ball pocket configurations in accordance with examples of the present invention will include 360 and 390 total pockets. The specific 45 of the 3rd and 3rd drawings 201208740 The pit configuration includes 390 all pits (and 5 pits per sector and 32·5 pits per half sector), and five different pit forms ( Forms eight to £) are placed on the ball 300. As shown in Figures 3A and 3B, the two adjacent sectors 302 can share a single recess such that each sector contains one half of the pit.

4A and 4B are respectively a plan view and a front view showing another example of a golf ball 4 in which one pit pattern is arranged in the manner described above with respect to the 3a and 3B drawings, and six full pit sectors. (there are two sectors in each of the pit pattern halves) and each sector is separated by a central symmetry line 1^, and the pits in the side-half sector are adjacent to the central symmetry line Ls in its adjacent half-sector A mirror image is formed in the area. In the illustrated example of the ball 4, the dimple pattern halves are rotationally offset from each other by about 60. . The particular pit configuration of Figures 4 and 4] 8 includes 360 total dimples, and each sector has four (four) dimples and each semi-fragment (5) is recessed. This ball 4GG includes six different dimple forms (forms A through F) configured to surround the ball. The top view and the front view of the golf ball 500 are shown in Figures 5A and 5B, respectively, in the case of the present invention, in which the fan and the half handle area can be provided.

Shown in the specific example of Figure 5B). In the figure, the ball 500 has half of each pit pattern divided into a plurality of sectors (shown by solid lines) and is symmetrical as (as shown by the dotted line of the 5A and the rotten line, each sector is reflected relative to the symmetry line LS. Most of the semi-sectoral areas. In order to be clear, there is no actual pit displayed in the 5th performance map, but in the manner of not biasing 46 201208740, Figures 6A and 6B are respectively shown in the manner described above with respect to the third and eighth figures.

In the example of the ball 600, the pit patterns are half of each other. The rotation offset is approximately 10. The specific pit configuration of Figures 6A and 6B includes 36 turns of all pits, and each pit has 30 pits and U pits per half sector. This ball 600 includes a configuration wrap.
